IMPROVEMENTVIN SUSPENSION-LAM PS.

Specification forming part of Letters Patent No. 218.228, dated August5, 1879; application tiled June 9, 1879.

To all whom it may concern Bc it known that I, EDSON L. BRYANT, ofAnsonia,in the county of N ew Haven and State of Connecticut, haveinvented a new Improvement in Suspension-Lamps; and I do hereby declarethe following, When taken in connection with the accompanying drawingsand the letters of reference marked thereon, to be a full, clear, andexact description of the same, and which said drawing constitutes partof this specification, and represents a side view With the weight-ringin section.

This invention relates t0 an improvement in that class of fixtures forsupporting lamps from the ceiling, and in which the arrangement is suchthat the lamp with its shade may belowered or raised to adjust the lightto different elevations, and commonly known in the trade as librarylamps 5 and the invention consists in the construction as hereindescribed, and particularly recited in the claims.

A is the lamp-fomit, supported in a suitable holder, here represented asa ring, B, attached to vertical rods C, more or less in number. Theserods or supports are provided with rests or stops a above the fount, andfrom cach of these rods or supports C a chain or cord, D, extends upover pulleys E above, thence outward and down, and attached to aring-shaped weight, F.

The pulleys E are arranged in a frame above, which is provided withmeans for attaching it to the ceiling or points where it is to besuspended.

The lamp is provided with any suitable burner, H, and onto this a shade,I, is placed. The support for the shade is here represented as a glassbottom, L, on the burner; but it may be supported from the lamp-supportsC, but within the chains.

Around the neck of the shade is a ring, d, provided with arms e,extending out toward the chains D, and so that the chains up from thesupport C pass outside the shade and through the said arms, the armsbeing provided with eyes or suitable pert'orations for that purpose, andpreferably so that they will produce a bend in the chain, as shown, andthereby cause a constant outward strain 011 the ring d.

When the lamp is drawn down the shade comes with it and the weight-ring,F, which is outside the shade, correspondingly rises; but when the lampis in its upper position the weight-ring rests on the stops c.

By connecting the shade at the top with the chains and at the bottomWith the lamp, or to the lamp-support, all liability to tip it (theshade) is avoided, and it is iirmly held in its position; but when it isdesiredto light or trim the lamp the shade may be raised, as indicatedin broken lines, the arms e running up the chain and still supportingthe shade, so that it cannot be accidentaliy dropped or thrown from thecontrol of the fixture.

I do not broadly claim an extension-lamp fixture in which the lamp andshade move construction I am aware is well known; but

What l do claim is- 1. The lamp-supports C, provided with stops a,combined with cords or chains, with their ends attached to said supportsoutside the shade, thence running up over pulleys outward, down, and theother ends attached to the weight-ring F, arranged to rest on said stopswhen the lamp is in its upper position.

2. The combination ot the lamp-supports C, provided with stops a and ashade held within said supports, with chains or cords, with their endsattached to said supports outside the shade, thence up over-pulleys,down outside, and the other ends attached to a Weight-ring outside saidshade and connection from the neck of the shade to the chains,substantially as described.
